title: Mucinous breast carcinoma presenting as Paget's disease of the nipple in a man: a case report.
abstract: BACKGROUND
  Male breast cancer is rare compared to its female counterpart representing less than 1% of cancer in men. Moreover, mucinous carcinoma of the male breast is an extremely rare histological subtype of malignancy. Paget's disease of the nipple is rarely observed in males.
  
  
  METHODS
  Herein, we describe a unique case of an 86 years old man with mucinous breast cancer presenting as Paget's disease of the nipple. According to the immunohistochemical evaluation the neoplastic cells were positive for estrogen (ER) and progesterone receptors (PR).
  
  
  CONCLUSIONS
  To our best knowledge this is the first case of mucinous male breast cancer presenting as Paget's disease of the nipple.
